Error while executing juju bootstrap microk8s: juju "3.3.1" can only work with strictly confined microk8s

[bobadair]

Hi. In the "Bootstrap controller" step I'm getting the error:
ERROR "/var/snap/juju/25912/microk8s/credentials/client.config" does not exist: juju "3.3.1" can only work with strictly confined microk8s

Here is the related step from the action:

       - name: Setup operator environment
        uses: charmed-kubernetes/actions-operator@main
        with:
          provider: microk8s

The full section of the log is:

You can see it in situ here: https://github.com/catalogicsoftware/cloudcasa-charm/actions/runs/7982420569/job/21795912102?pr=6

I'd suspect something set up wrong in my environment, but I don't really see anything obvious.

@bobadair i happened across your situation here and wondered if you found that you can specify the strict version of microk8s here? juju 3.3 and beyond (i recommend using 3/stable) needs a strict channel version of microk8s

   with:
      provider: microk8s
      channel: 1.31-strict/stable
